The steel ball valve core has good pressure resistance, but the disadvantage is that the rubber ring that acts as a seal is easy to wear and will age quickly. Compared with the steel ball valve core, the ceramic valve core is more heat-resistant and wear-resistant. At the same time, the ceramic valve itself has good sealing performance, so it can achieve a high resistance to opening times, and the nozzle will not leak due to the wear of the valve core. The ceramic valve core is more comfortable and smooth in hand, and it opens and closes quickly. Because the valve core is inside the water, consumers cannot see the valve core when purchasing, but consumers can simply judge the quality of the valve core according to the feel of the handle when turning the handle. Generally speaking, consumers turn the handle up, down, left and right. If it feels light and has no blocking feeling, it means that the valve core is better. dedecms.com Recognize a brand: choose a brand for better after-sales service In the end, consumers should go to regular markets and supermarkets to buy brand water.
